The director of a large NHS trust has contacted the BBC asking for the phone numbers of Burberry and Barbour because he does not have enough gowns for his staff working on coronavirus wards.
He said his trust has "less than 24 hours supply and [with the] weekend coming up" he was hugely concerned.
The BBC is not disclosing his name or the trust he runs.
The Department of Health said it was working "around the clock" to provide protective equipment where needed.
For a number of weeks, Prime Minister Boris Johnson and government ministers have said during press briefings and interviews that Burberry will begin making personal protective equipment (PPE) on behalf of the government as one of the answers to a critical shortage of PPE.
Burberry said at the end of March it would repurpose its trenchcoat factory in Castleford, West Yorkshire, to make non-surgical gowns and masks for hospital patients.
The government has been criticised for not providing enough PPE for NHS and other care workers to protect them in their work.
Last week Health Secretary Matt Hancock said there was "enough PPE to go around, but only if it's used in line with our guidance", adding there was a "huge task" to make sure those who need it get it.
However, on Wednesday the NHS Trust director said: "The official line that we don't have a shortage of PPE is fantasy."
A gown is a piece of PPE used to protect the body of those who might come into contact with coronavirus.
It should be made of water-resistant material and have long sleeves. If the gown is not water resistant, a waterproof apron is needed underneath to protect the wearer from droplets containing the virus.
The shortage of non-surgical gowns is a critical problem facing the NHS as it struggles to secure enough personal protective equipment (PPE) for frontline staff.
The situation at this particular trust is so critical that single use PPE is being reused.
A leaked Public Health England document this week advised health workers to reuse protective gowns and masks only as a "last resort".
The boss added "Trusts are already decontaminating PPE for reuse. I have several examples".
In messages and phone calls that followed, the NHS boss said that they were investigating using hydrogen peroxide, normally used as bleach, to sterilise PPE, including masks.
As the world fights coronavirus, the demand for gowns is unprecedented and at levels never seen before.
Almost all of the UK's supply of gowns used by the NHS is made in China and the Far East.
These decisions have been driven by cost, as all sectors seek the cheapest prices.
But as every country in the world fights for finite supplies, a UK solution has been sought.
The government and management consultancy Deloitte approached well known UK garment brands asking if they can help make PPE.
They also requested that UK manufacturers complete a survey to share what they could make.
Earlier this week, Barbour began distributing gowns from its factory in the north east of England.
Burberry is still making the final adjustments to its factory and production is expected to start next week.
Getting a supply chain formalised using UK factories has been difficult.
UK garment factories approached by the BBC have said the government doesn't fully understand what is possible in the UK, and which firms could produce what. This lack of understanding has caused production delays.
